    ions and electrons, the positive ions are attracted to the outside of the tube. The electrons are attracted to a metal wire running down the inside of the tube maintained at a high positive voltage. Many electrons travel down the wire making a burst of current in a circuit connected to it. The electrons make a meter needle deflect and you can hear a click every time radioactive…

    The protons are positively charged particles that are also located in the nucleus and symbolized as p+. The second part of an atom is the electron cloud. The electron cloud is a cloud of electron which surrounds the nucleus. The electrons are the third type of subatomic particle- along with protons and neutrons. Located outside of the nucleus, electrons are negatively charged. Due to their location and their ability to react with…

    how it is able to bond with other molecules and how effective these bonds are. The structure of the molecule itself is held together by the intramolecular forces, which are the internal forces of a molecule, such as the attraction and repulsion of electrons to the protons in the nucleus. The external forces on a molecule, which are called the intermolecular forces, such as electronegativity, help to determine the boiling and melting points of each element. Each of these intermolecular forces…

    determined by the electrons in a compound.1 As electrons move around, they can absorb energy and become excited. The energy, and thus the wavelength of light, the electrons absorb is determined by the type of atoms found in the compound and how those atoms are bound together. Different environments for electrons will also determine how much of a particular wavelength of light can be absorbed, a parameter which is reflected…

    oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between two non-metals, the molecules share electrons to achieve full valence shells for the molecule to be stable. In the case of water the two hydrogens and one oxygen share electrons to get the hydrogen molecules with two electrons in their outer shells and…

    are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they used the word “atomos” to describe something that is uncuttable. This idea was not found by…

    1 on the periodic table. Hydrogen has an atomic mass of 1 and an atomic number of 1. Hydrogen has 1 VALENCE electron and 1 neutron. It has 1 ring, because it’s in period 1. Hydrogens state of matter is gas. Lithium is a Alkali Earth Metal on the Periodic Table. Lithium's state or matter is solid. Lithium has a atomic number of 3 and an atomic mass of 7 when rounded. It has 1 valence electron around its nucleus and 4 neutrons in the nucleus. Lithium has 2 rings because of its period. Beryllium is…

    Lewis chose a three-dimensional structure that contained eight vexes as representations for valence electrons. Consequently, he chose the cube because it contains eight vexes. Its orderly shape appealed to the common scientific notion that the universe contains patterns and organization. A conceivable structure like the cube allowed for easy application…

    The problem with synthesizing this molecule is that it contains unpaired electrons in two of its outer carbons. These free electrons cause the molecule to oxidize almost instantly as these electrons react to try to find stability. The researcher team form IBM has found a way to overcome this obstacle. By starting with the molecule dihydrotriangulene, triangulene with a hydrogen attached to each of the unpaired electrons. The researchers were able…

    He was able to find the charge of an electron with an experiment involving passing oil through an electrically charged plate with a hole in the center. Using this newfound charge and the determined mass-to-charge value of an electron, “you obtain an electron mass of 9.109 x 10-31 kg, which is more than 1800 times smaller that the lightest atom” (Ebbing and Gammon, 47). Some years later, in 1911,…
